You can put this solution on YOUR website! We can either convert to decimals or work with the fractions. Since 18 isn't a good decimal, let's use the fraction.
64 * 3 = 192 / 4
61 * 11 = 671 / 18
What is the lowest common denominator for 4 and 18?
4,8,12,16,20,24,28,32,36,40
18, 36, 54
-- 36, so let's put the fractions into 36ths
192/4 = 192*9 ... 1728/36
671/18 = 671*2 ... 1342/36
.
1728 - 1342 = 406/32
Reduce to 12 22/32
Reduce the fraction 12 11/16
